89, and it's not Fahrenheit? That leaves Celsius and Kelvin (I heard that there is another, but I can't verify such a statement). 89 degrees Celsius would horribly burn the throat of anyone who drank it, and 89 K would leave a cup of iced coffee! (Quick riddle: if frozen water is iced water, what is frozen ink?)O-a in LA

Oooh - a scientific discussion about the temperature of coffee! Great! <IMG SRC="http://www.keenspace.com/forums/smile.gif"><P>Here are the premises the temperature of 89C are based on. Discuss. - Coffe is made with boiling water.- Water boils at 100C- By the time the coffe is in the cup it's temperature has dropped a bit, say 10 degrees.- UK coffee machines serve coffee and tea at 90C. In flimsy plastic cups.<P>Conclusions: - 89C is a good assumption for the initial temperature of coffe in the UK.- The British have a masochistic streak. Then again, if you've ever tasted British coffee, you already know that.- Chief Phipps' ship was manufactured in the UK. Like the Titanic. Oops...
